As I have been noting, there was a void of key level until 155.20 other than the 200 day mva (151.37), break of which propelled USDJPY higher, and a 61.8% FIBO.
Now 152 becomes pivotal as the level that needs to hold keep a strong bid and put 155.20 on the radar.
Note, the correlation between the JPY and firmer US yields.
Risk of verbal intervention rises given pace of JPY slide.
